- The twentieth century saw rapid environmental degradationdue to changes that contributed to increased net GHG emissions, loss of natural ecosystems, and declining biodiversity. Deterioration of unprotected landscapes during swift industrialization, urbanization, increasing monocultures in agriculture, expansion of commercial production significantly contributed to thesenegative consequences. However, a cultural shift occurred during the last two decades in favour of landscape conservation. In response to widespread landscape degradation and loss of ecosystem services, the Council of Europe saw the need to protect, manage, and develop the landscapes, and thus signed the European Landscape Convention (ELC) in 2000. This was the world's first international agreement that described all aspects of landscape management in detail. The European Landscape Convention fully meets the challenges through its goal of correcting a lack of understanding of landscapes as a unique system embracing natural, economic, and social features throughout Europe. It goes beyond simply protecting landscapes and addresses landscape management and development, as well as raising public and government awareness of the importance of paying attention to all types of landscapes, whether exceptional or spoiled. Landscapeobservatories, multifunctionalplatformsand knowledge centres for researchers, technicians, administrators, and citizens,are one of the Council of Europe's instruments for implementing the European Landscape Convention (ELC). They can be established on a variety of scales and can serve as a vital link between administrations, civil society, researchers, and the economic sector. This article discusses the emergenceof landscape observatories and the role they can play as decision support instruments in promoting sustainable landscape developmentthrough a regenerative approach. Additionally, the paper discusses the implementation of ELC in Västra Götaland in Sweden through the establishment of Landscape Observatory Västra Götaland, and its impacts and challenges associated with landscape development.Furthermore, we propose a comprehensive and holistic, to any landscape type adaptable landscape observatory concept, based on multifunctionality of these institutions, emphasizing their decision support roles, social and economic importance.

- The wood in the 17th century Swedish warship Vasa is weak. A depolymerization of the wood's cellulose has been linked to the weakening, but the chemical mechanisms are yet unclear. The objective of this study was to analyze the lignin and tannin moieties of the wood to clarify whether the depolymerization of cellulose via ongoing oxidative mechanisms is indeed the main reason for weakening the wood in the Vasa. Lignin was analyzed by solid-state nuclear magnetic resonance [cross-polarization/magic-angle spinning (CP/MAS) C-13 NMR] and by means of wet chemical degradation (thioacidolysis) followed by gas chromatography-mass spectrometry (GC-MS) of the products. No differences could be observed between the Vasa samples and the reference samples that could have been ascribed to extensive lignin degradation. Wood extracts (tannins) were analyzed by matrix- assisted laser desorption ionization (MALDI) combined with time-of-flight (TOF) MS and C-13 NMR spectroscopy. The wood of the Vasa contained no discernible amounts of tannins, whereas still-waterlogged Vasa wood contained ellagic acid and traces of castalagin/vescalagin and grandinin. The results indicate that the condition of lignin in the Vasa wood is similar to fresh oak and that potentially harmful tannins are not present in high amounts. Thus, oxidative degradation mechanisms are not supported as a primary route to cellulose depolymerization.

Tidskriftsartikel (refereegranskat)abstract
- George Floyd’s murder by a white policeman has sparked the largest urban uprising in US cities since the 1960s. By contextualising this wave of uprisings in the broader context of similar uprisings in twenty-first-century US cities, this paper shows that such an uprising has long been in the making with the violence, murders and revolts that have marked US cities since the turn of the century. My argument in this paper is against the pathological framing of these uprisings that evokes the alleged irrational anger of those who participate in the uprisings and the bad behaviour of a few police officers. Such a framing directs attention away from the structural violence that is at the source of these uprisings, and perpetuates racialised images of those who participate in the uprisings as irrational and impulsive. These uprisings, I argue, are not the actions of irrationally angry individuals mindlessly following the crowds; they cannot be reduced to gratuitous looting and burning, and they are not triggered by some police officers behaving badly. The sources of this urban rage lie in systematic, mostly unchecked, violence. The rage that erupts in these uprisings is a political emotion guided by cognition and judgements about right and wrong, just and unjust, rather than a pathological reaction spurred by uncontrollable impulses. It is a deliberate response to white contempt and the violence associated with it. The information, practices and views in this article are those of the author(s) and do not necessarily reflect the opinion of the Royal Geographical Society (with IBG).

District heating as a flexibility service: Challenges in sector coupling for increased solar and wind power production in Sweden
- 2023
-
Ingår i: Energy Policy. - : Elsevier BV. - 0301-4215 .- 1873-6777. ; 172

Tidskriftsartikel (refereegranskat)abstract
- With expanding solar and wind power production, the topic of flexibility services attracts increased attention in the Swedish energy system. In this context, the potentials in using thermal storage capacities in district heating (DH) systems have been brought forward, primarily by academic scholars. Using a ‘grounded’ approach, this study investigates if professionals assigned to Swedish DH companies and electricity distribution system operators utilise, or plan to utilise, DH systems as flexibility services for the electricity grid. Original data was collected through semi-structured interviews, held with fourteen individuals affiliated to different actors in the Swedish energy system. These individuals were identified as being experts, or practically engaged, in using DH utilities as flexibility services for the electricity grid. The findings show that although technologies for coupling between DH systems and the electricity grid are already in place, initiatives for using DH systems as flexibility services for the electricity system are rare in Sweden. Coupling challenges stem from ownership and operation legislation frameworks, marginal incentives and a widespread focus on firm benefits rather than energy systems benefits. Identified initiatives for using DH systems for flexibility services are primarily run on a local scale, designed and propelled by small groups of engaged individuals.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This essay uses the quandary facing Swedish security policy decision-makers in 1863 as a starting point to discuss a few timeless topics of national strategy. Affected by pan-Scandinavian sentiments, in July 1863 Charles XV made a declaration of solidarity with Denmark, which faced a military threat from the German Confederation, promising Swedish troops to help defend the southern border of the Duchy of Schleswig. However, the King had not secured the support of his cabinet, which refused to back the King’s policy, so that despite intense diplomatic activity, no military assistance to Denmark was given when the Second Schleswig War eventually started. Using this historical experience as a case-study, observations and reflections are made about the security policy of small states, about the need to coordinate and de-conflict policy initiatives within the core executive, and about what is required for a declaration of solidarity to be credible.

Konferensbidrag (refereegranskat)abstract
- In this one-day workshop we are going to make access. We aim to counteract the phenomenon that access to making (e.g., in makerspaces, fablabs, etc.) is not equally distributed, with certain groups of people being underrepresented (e.g., women∗1). After brief introductions from participants and a set of three impulse keynotes, we will envision and "make"interventions together, such as speculative or provocative objects and actions. The workshop takes a constructive stance with the goal to not rest on empirical and theoretical findings or individual experiences, but to translate those into viable interventions. These serve as exemplars of findings with the clear goal of being deployed soon after.

Managerial and organizational challenges encountered in the development of sustainable technology : Analysis of Swedish biorefinery pilot and demonstration plants

Tidskriftsartikel (refereegranskat)abstract
- Pilot and demonstration plants (PDPs) perform critical tasks in the development of new sustainable technology by bridging basic knowledge generation and large-scale commercialization. Significant private and public funding has therefore been allocated to PDPs addressing climate change, pollution abatement technology and/or increased resource efficiency. After technology verification, PDPs typically struggle with evolving objectives, and reports of stalled or delayed development are common. Key problems may center on technical difficulties, but challenges of a non-technical nature are equally important, not least for the development of clean technology. This paper draws on a longitudinal case study of four PDPs used for advanced biorefinery technology development in Sweden and delineates the key managerial and organizational challenges that arise in and around such plants. By taking the actor networks around PDPs as the main unit of analysis, this paper gives a detailed description of various challenges, such as the division of responsibility for the operation and ownership of the PDPs, unclear roles and objectives, and the lack of specific competences and resources in the actor networks. One important conclusion is that improved knowledge about such challenges should increase the resilience of actor networks in and around PDPs, and also help shorten the formative phase of developing sustainable technology. © 2020 The Authors

Bok (övrigt vetenskapligt/konstnärligt)abstract
- Um Denkmäler zu bewahren und Altbauten für eine zeitgemäße Nutzung instand zu setzen, sind Lösungen notwendig, die den Eigenschaften und dem Erhaltungszustand der Gebäude angepasst sind. Dazu ist ein Grundwissen über historische Baustoffe erforderlich. Reparaturmaterialien interagieren physikalisch und chemisch mit dem Bestand. Falsche Reparaturversuche können Schäden verschlimmern oder neue Schäden hervorrufen. Dieses Buch ist eine Baustoffkunde der seit Jahrtausenden gebräuchlichen Materialien Lehm, Kalk, Gips, Naturstein und Ziegel. Behandelt werden außerdem Zementmörtel und historische Betone sowie unterschiedliche Farben und Pigmente. Ein Kapitel ist dem Asbest gewidmet. Der Autor beschreibt die Geschichte der Entstehung oder Herstellung dieser Baustoffe, ihre stoffliche Zusammensetzung und die Materialeigenschaften. Ein wesentlicher Teil des Buches befasst sich mit naturwissenschaftlichen Grundlagen und Analysemethoden, mit denen Materialzusammensetzungen bestimmt und Schadensursachen aufgeklärt werden können. Dieses Grundwissen benötigen Planer, damit sie baustoffkundliche Untersuchungen gezielt beauftragen und fundierte Entscheidungen für Maßnahmen zum Schutz, zur Konservierung oder zur Instandsetzung treffen können. Das Buch ist Teil der Reihe »Erhalten historisch bedeutsamer Bauwerke - Empfehlungen für die Praxis«. Diese Buchreihe stellt in thematisch abgegrenzten Einzelbänden konzeptionell-entwurfliche und bautechnisch-konstruktive Methoden für einen behutsamen Umgang mit historischer Bausubstanz vor, bei dem Eingriffe auf das wirklich Notwendige beschränkt werden. Sie gründet auf einer gleichnamigen, vor genau 20 Jahren von Fritz Wenzel und Joachim Kleinmanns herausgegebenen Publikationsreihe, in der die Ergebnisse des Sonderforschungsbereichs 315 »Erhalten historisch bedeutsamer Bauwerke - Baugefüge, Konstruktionen, Werkstoffe« veröffentlicht wurden.

- Future transportation systems will be a heterogeneous mix of items with varying connectivity and interoperability. A mix of new technologies and legacy systems will co-exist to realize a variety of scenarios involving not only connected cars but also road infrastructures, pedestrians, cyclists, etc. Future transportation systems can be seen as a System of Systems (SoS), where each constituent system - one of the units that compose an SoS - can act as a standalone system, but the cooperation among the constituent systems enables new emerging and promising scenarios. In this paper we investigate how to architect cars so that they can be constituents of future transportation systems. This work is realized in the context of two Swedish projects coordinated by Volvo Cars and involving some universities and research centers in Sweden and many suppliers of the OEM, including Autoliv, Arccore, Combitech, Cybercom, Knowit, Prevas, ÅF-Technology, Semcom, and Qamcom.
